How is DNA arranged in molecules?

Answer 1

DNA stands for Deoxyribonucleic acid and is the blueprint for the human body. The shape is a double helix it looks like a twisted latter, each foot step in the "ladder" is made up of protein. There are four types of proteins: Guanine, Adenine, cytosine, and thymine. Guanine pairs with cytosine and adenine pairs with thymine. The pairs extend from each "step in the ladder" on opposite sides to connect and form a trait. This makes up you. Also DNA is only individual to one person, except for identical twins and clones.

Answer 2

DNA is composed of many nucleic acids bound by covalent and hydrogen bond. The five carbon sugar(deoxyribose) attached to the phosphate group is joined to one another to form the sides of the DNA, forming a covalent bond of sugar-phosphate-sugar-phosphate etc. Also, one of 4 nitrogen bases of DNA are attached to the sugar, which is in turn attached to each other. The purines(double ringed base) which are A and G bond with the pyrimidines T and C respectively. The bonding between the two creates a hydrogen bond. Together with all these reactions, DNA is formed and looks like a twisted ladder, or a double helix.

Answer 3

DNA is constructed of two long polynucleotide strands wound together in a right-handed double helix. Each nucleotide is formed of a sugar (2-deoxyribose), a phosphate group, and a nitrogenous base, which will be either adenine, guanine, cytosine, or thymine. Adenine and guanine are purines, meaning they have a double ring structure and four nitrogens. Cytosine and thymine are pyrimidines, which have a single ring structure and only two nitrogens. A purine is always paired with a pyrimidine, when the DNA is found in its stable double-stranded state, and the pairings are always adenine with thymine and cytosine with guanine. Adenine and thymine form two hydrogen bonds, while cytosine and guanine form three.

DNA strands have a 5' end and a 3' end. The 5' end is characterized by a phosphate group coming off of the fifth carbon in the sugar. The 3' end exhibits an OH group protruding from the third carbon of the sugar. The strands always pair anti-parallel to one another in the double helix, meaning that the 3' end of one strand will be on the same end as the 5' end of the other. Finally, the double helix structure creates alternating major and minor grooves within the helix.

Answer 4

the phosphate group grow two small glands called binary testicals and then inserts a rod like shaft into the center of the membrane on the sugar molecules and have sexual reproductiong producing dna

Answer 5

DNA is arranged in a double helix structure, where two strands of nucleotides are twisted around each other. The nucleotides are composed of a sugar-phosphate backbone with nitrogenous bases adenine pairing with thymine and guanine pairing with cytosine. This arrangement allows for genetic information to be stored and replicated accurately.
